HENRY BRADY, OF BLOOMFIELD, AND ADIN VI. HILSIITGEB, OF ORANGE, NEW JERSEY, ASSIGNORS TO HENRY BRADY, INC., A CORPORATION OF NEVI JERSEY.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed August 11, 1916. Serial No. 114,352.

To all 'whom 'it may concern Be it known that I, HENRY BRADY, a citizen of the United States, and residing at Bloomfield, county of Essex, tate of New Jersey, and I, ADIN W. HILsINGnR, a citizen of the United States, residing at Orange, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Feeding Mechanism for Box-Making Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to improvements in box making machinery and more particularly has reference to feeding mechanism adapted for feeding paper, Card board or similar material from which the boxes are to be made into the machine and is an improvenient on the feeding mechanism in copending patent application to Henry Brady, Serial No. 837,302, filed Nov. 11, 1919.

Referring to the accompanying drawing marked Figure 1 we have illustrated therein in perspective view with parts broken away an application of our invention. 2 indicates a suitable base or support upon which the standards 3-4 are mounted and likewise the standards 5 6. The standards first mentioned are adapted to support the frame w rk 7 within which the shaft 8 is mounted and upon which is secured the pulley 9, adapted to be driven by a belt such as 1() or other suitable means. The end of the driven shaft 8 is also provided with a pinion such as 11 which meshes with the pinion or gear 12 upon the shaft 13 which is provided at the opposite extremity with a sprocket 14, provided with the sprocket chain 15 which in turn passes over the sprocket 16 upon the shaft 17, also secured upon the standards 3 4. Said shaft 17 is also provided with a pulley 18 which drives the belt 19 over the pulley 20, said last mentioned pulley being mounted in the end of the bar 21 which has an extension or projection 22 and rests upon the shaft 17 allowing said shaft to freely rotate thereon and it is provided with a weight such as 28 which serves to keep the pulley and its belt 19 against the periphery of the roll of paper or board 24 mounted upon the shaft 25 in the top of the standards 5--6.

F rom the foregoing it will be readily understood that as the pulley 9 is driven by the belt l0 the pinion 11 upon the same shaft, drives the pinion 12 and the sprocket 1l upon said shaft. This in turn drives the shaft 17 through the sprocket 16, and the belt thereby travels in the direction of the arrow against the peripheral face of the paper roll 2%, thus causing the same to feed leftly in the machine as indicated by the arrow at the top to the rolls 26-27 and the roll 26 is mounted upon a suitable shaft or spindle as shown. 28 is a pinion which meshes with the rack 29 which is pivotally connected at 30 to the lever 31 upon the shaft 13 so that as said shaft 13 rotates, the rack 29 serving` as a connecting rod reciprocates and its teeth being in engagement with the pinion 28 cause the same to rotate first in one direction and then in the other. Suitable rachet mechanism not shown is provided so as to cause the pinion 28 to rotate the shaft or spindle of the roll 26 when turning in one direction only, thus being free to move in the reverse direction. Such mechanism is shown in copending patent application referred to, and as such mechanisms are well known it is not deemed necessary to make further disclosure herein. The result is that the paper is fed intermittently in the same direction in the machine, thus allowing the same to be cut off in predetermined lengths and to be folded and finished in any desirable manner thereafter.

532-33 indicate suitable fingers or guides for engaging the opposite edges of the paper for controlling the same as it enters the machineL Of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

IVe claim:

l. In a machine of the class described, a supply roll and a mechanism for controlling the. slack of the web as it is fed therefrom, said mechanism comprising an endless belt adapted to be driven against the periphery of said roll, and means for adjusting the tension of said belt whereby the slack in said web may be regulated.

2. In a machine of the class described, a supply roll and a mechanism for controlling the slack of the web as it is fed therefrom, said mechanism comprising an endless belt adapted to be driven against the periphery of said. roll, and means for adjusting the tension of said belt whereby the slack n said web may be regulated, said tension ad- 5 -justng means comprising a pvoted counterweight for controlling the pressure of said belt upon said roll.

In testimony whereof We hereunto afx our signatures n the presence of two Wit nesses.
